The posthumous paper of Hermann Haupt on the classification 
of the Macromerinae (Haupt, 1959) is an unworthy memorial to 
its author and an unfortunate step backward in the systematics of 
spider wasps. Working from very little material and a lack of 
awareness of research in other parts of the world, Haupt erected 
12 new genera, few if any of which are likely to stand the test of 
time. Two of them actually belong in the subfamily Pompilinae, as 
synonyms of Priochilus Banks (Evans, 1966), while others will fall 
in the Pepsinae in most classifications ( Compsagenia , Anapriocnemis) . 
H is inclusion of such diverse elements in the Macromerinae suggests 
the difficulty in defining the group, which I would rank as a rather 
weakly characterized tribe of Pepsinae and call the Auplopodini, 
after the first genus to be used in a suprageneric sense, Pseudagcnia , 
now properly called Auplopus. 
I am not in a position to straighten out all the confusion caused 
by Haupt’s paper, but I wish to consider seven genera which he 
described from the neotropics, all of which can be promptly rele- 
gated to synonymy. There are, however, several remarkable new 
genera and subgenera of this tribe in South America, wdiich both 
Haupt and Banks (1946) were unaware of, and I shall use this 
opportunity to describe these taxa and to present a revised key to 
neotropical Auplopodini. 
I am much indebted to Professor J. O. Hiising, of the Zoolo- 
gisches Institut, Halle, for permitting me to borrow some of the 
specimens that Haupt studied, including several types.
